Hello everyone,
I have a rather specific question that came up during the assembly of my Billy shelf: Which screws are considered the strongest and most durable for BILLY?
I’m particularly interested in which screws are best suited for load-bearing parts, basically maximizing the shelf’s stability.
I want to avoid any screw failure or the shelf becoming misaligned over time. I understand there are different types of screws, such as particleboard screws, wood screws, or even special screws from IKEA itself.
Does anyone have experience with which screws actually provide the best stability when used with BILLY? I’m looking forward to your tips and ideally some advice on whether it makes sense to replace the original screws or to use additional ones.

Hey Farkau30,
your question is really well thought out! 🙂
Personally, I would always go for the original IKEA screws. They might not be the toughest in terms of hardness, but they are perfectly matched to the material thickness and design of the BILLY. If you want to be extra sure, you can also add metal brackets – that will provide even more stability.
Regarding the screws: chipboard screws with fine threads are actually the best choice, as they provide the strongest hold. Just using thicker screws won’t help if the holes are already fixed.
Hope this helps you for now! 😉

Which screws are considered the strongest and most durable for BILLY?This is a really interesting question, especially since the BILLY system’s construction heavily relies on the use of particleboard. You achieve the best stability, subjectively, by using screws specifically designed for particleboard material. This means screws with fine, consistent threads that embed into the wood material without splitting or breaking it.
Usually, these are particleboard screws with a diameter of 4.0 to 5.0 mm (0.16 to 0.20 inches) and a length of 35 to 40 mm (1.4 to 1.6 inches), as Ellis already mentioned. I also recommend screws with a countersunk head so that the screw head sits flush with the surface, avoiding any pinch points or unevenness.
Important: Buy high-quality screws with good zinc plating or even stainless steel, since cheaper screws tend to rust faster and don’t drive in as smoothly. Pay close attention to the screw tip – a self-tapping tip makes driving the screw significantly easier.
One last tip: pre-drilling is usually not necessary because particleboard accommodates screws well. However, if you know from experience that screws tend to strip out quickly, you can drill a pilot hole with a thinner drill bit to increase load capacity.
What kind of load are you specifically looking to support? More compressive or tensile? That way, I can provide more tailored advice.

Basically, my main concern is the lateral load, meaning when the shelf is fully loaded and pressure is applied forward or from the side. Loads along the back wall are less critical since stability is best there anyway.
Another point is the connection between the individual shelves and the side walls – I want no wobbling, especially with frequent use and heavy contents (books).
I hope this description helps.

I recommend adding metal angle brackets in addition to the original screws. These distribute the loads much more effectively and prevent the screws from being pulled out due to lateral forces.
If you prefer to use screws only, make sure to use chipboard screws with a full thread and countersunk heads, at least 40 mm (1.6 inches) long, to ensure a good grip in the material.
Using stainless steel screws (grade A2 or A4) is also advisable if the shelf is placed in more humid rooms, so that the connection retains its strength over the years.
Important: Do not use screws that are too thick, as this can cause the wood to split!
